[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies and application scenarios of the dry cooler are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0026] A dry cooler is a dry cooler, and no water is consumed during its working process. In the related art, a dry cooler generally cools the liquid in the tube by letting the liquid flow inside the tube and letting natural wind flow outside the tube, thereby reducing the temperature of the liquid in the tube and achieving the purpose of cooling. A dry cooler may include a wet curtain, a cooling water dry coil, and a fan. Among them, the wet curtain is used to cool the outdoor air entering the wet curtain, and the cooling water dry coil is used to contact the cooled air so that the temperature of the cooling water in the cooling water dry coil is reduced to a predetermined temperature. The cooled cooling water (hereinafter referred to as cooling cooling water) can be used to cool other equipment such as computers. The fan is used to discharge the heated air after contacting the cooling water dry coil.

[0027] Figure 1An exemplary application scenario of a dry cooler is shown. In this application scenario, the dry cooler can be used for heat dissipation of a computer. Specifically, the dry cooler can be used to deliver cooling water to a liquid cooling device. The cooling water delivered to the liquid cooling device is used to perform heat exchange with the computer to cool the computer and achieve heat dissipation. Here, the computer may include a server in a data center for providing data computing and storage services; the liquid cooling device may include a device for containing cooling water and using a cold plate, immersion, spraying, etc. to bring the cooling water into direct or indirect contact with the computer, such as a cold plate fixed on a computer heating device, a box for immersing the computer, a liquid reservoir with an opening, etc. The temperature of the cooling water after cooling the computer rises, and the heated cooling water is delivered to the dry cooler, which continues to deliver the cooling water by cooling the heated cooling water.

[0028] The embodiment of the present application is mainly to solve the problem of insufficient heat dissipation capacity of dry coolers in extreme environments in the related art. In order to be able to understand the characteristics and technical content of the embodiment of the present application in more detail, the implementation of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiment of the present application.

[0029] Embodiment 1

[0030] Figure 2 FIG. 2 shows a schematic diagram of the structure of a dry cooler according to Embodiment 1 of the present application. Figure 2 As shown, the dry cooler includes a second heat exchange system 200 and a first heat exchange system 100 .

[0031] The first heat exchange system 100 is used to perform heat exchange between liquid refrigerant and heated cooling water to obtain gaseous refrigerant and cooling water for cooling the computer, and the gaseous refrigerant is transported to the second heat exchange system 200 .

[0032] The second heat exchange system 200 is used to cool the outside air to convert it into cooling air, and to perform heat exchange between the gaseous refrigerant and the cooling air to obtain liquid refrigerant, and then transport the liquid refrigerant to the first heat exchange system 100 .

[0033] In this embodiment, the heating cooling water may refer to the cooling water after absorbing the heat emitted by the computer, and may also be referred to as cooling water return water. Similarly, the cooling cooling water may refer to the cooling water cooled after heat exchange with the liquid refrigerant, and because it is used to dissipate heat for the computer, it may also be referred to as cooling water supply water.

[0034] In this embodiment, the outside air may refer to the air outside the second heat exchange system 200. In practical applications, the second heat exchange system 200 may be set at the air outlet of the IDC room, and the outside air is the air outside the room. Optionally, the second heat exchange system 200 may be implemented by a wet curtain. For example, in the second heat exchange system 200, the moisture on the surface of the wet curtain may be used to cool the outside air. The cooling air in this embodiment is the air that has been cooled after passing through the wet curtain.

[0035] According to the above embodiment, on the one hand, the first heat exchange system 100 of the dry cooler uses liquid refrigerant to absorb the heat of cooling water to cool the cooling water; at the same time, the liquid refrigerant is heated and vaporized to form a high-temperature gaseous refrigerant and then enters the second heat exchange system 200. On the other hand, the second heat exchange system 200 of the dry cooler uses cooling air to exchange heat with the gaseous refrigerant to liquefy the refrigerant and cool it down. The cooled liquid refrigerant enters the first heat exchange system 100 again to achieve a circulation flow. It can be seen that the above embodiment adds the first heat exchange system 100 to the dry cooler product that uses cooling air for heat exchange, realizes the heat exchange between cooling air and refrigerant, and the heat exchange between refrigerant and heated cooling water, and uses the circulation power and refrigeration capacity provided by the first heat exchange system 100 to improve the heat dissipation capacity of the dry cooler, which is conducive to ensuring the stability of the operation of the IDC system.

[0036] Optionally, in the first heat exchange system 100, the gaseous refrigerant can be processed in some way. For example, before the gaseous refrigerant is transported to the second heat exchange system 200, the gaseous refrigerant can be compressed so that the gaseous refrigerant enters a high-temperature saturated state. That is, the liquid refrigerant exchanges heat with the heated cooling water, so that the liquid refrigerant absorbs the heat of the heated cooling water and vaporizes to form a gaseous refrigerant. The gaseous refrigerant at this time is in a high-temperature state. After compressing the high-temperature gaseous refrigerant, the gaseous refrigerant becomes more high-pressure / saturated, that is, the gaseous refrigerant at this time is in a high-temperature and high-pressure state. In the second heat exchange system 200, the gaseous refrigerant, which is a high-temperature and high-pressure saturated gas, releases heat to the outside when it is cooled, and then reliquefies into a liquid refrigerant. By compressing the gaseous refrigerant, it is beneficial to fully liquefy and cool down in the second heat exchange system 200, thereby improving the heat exchange efficiency.

[0037] Embodiment 2

[0038] Figure 3The structural schematic diagram of the dry cooler according to the second embodiment of the present application is shown. Based on the first embodiment, this embodiment provides a specific implementation of the second heat exchange system 200 and the first heat exchange system 100. It should be understood that the specific implementation of the second heat exchange system 200 provided in this embodiment is an optional but not necessary implementation. Similarly, the specific implementation of the first heat exchange system 100 provided in this embodiment is also an optional but not necessary implementation. In practical applications, those skilled in the art may also choose other embodiments to implement the second heat exchange system 200 and / or the first heat exchange system 100.

[0039] In this embodiment, the second heat exchange system 200 includes a wet curtain 21, a dry coil 22, and a fan 23. The wet curtain 21 is used to cool the outside air to cool the air. The dry coil 22 is used to exchange heat between the gaseous refrigerant and the cooling air to obtain liquid refrigerant and heated air. For example, the dry coil 22 allows the gaseous refrigerant to exchange heat with the cooling air by flowing the gaseous refrigerant in the tube. The fan 23 is used to transport the heated air to the outside of the second heat exchange system 200.

[0040] For example, Figure 3 As shown, the second heat exchange system 200 may further include a spray water pump 24 and a water pan 25, wherein the spray water pump 24 may spray water evenly onto the wet curtain 21 to keep the surface of the wet curtain 21 moist, so that when the outside air passes through the wet curtain 21, the water on the surface of the wet curtain 21 evaporates and absorbs heat, causing the air to enter the dry cooler after cooling. Excess unevaporated water may be discharged from the bottom of the wet curtain 21, collected in the water pan 25, and then sent to the wet curtain 21 again by the spray water pump 24 in a spraying manner.

[0041] For example, the heat exchange between the gaseous refrigerant in the dry coil 22 and the cooling air can be achieved by the contact between the dry coil 22 and the cooling air. The gaseous refrigerant releases heat when it is cooled and reliquefies into liquid refrigerant. The cooling air absorbs the heat released by the gaseous refrigerant and its temperature rises, thereby forming warmed air, which is discharged out of the system by the fan.

[0042] In this embodiment, the first heat exchange system 100 includes a compressor 11, a fluorine pump 12 and a water-refrigerant heat exchanger 13. The fluorine pump 12 is used to transport the liquid refrigerant to the water-refrigerant heat exchanger 13, and the water-refrigerant heat exchanger 13 is used to heat exchange the liquid refrigerant with the heated cooling water (cooling water return water) to obtain a gaseous refrigerant and a cooling water (cooling water supply water) for cooling the computer. The compressor 11 is used to compress the gaseous refrigerant so that the gaseous refrigerant reaches a high-temperature saturated state and then transports the gaseous refrigerant to the second heat exchange system 200. Specifically, the fluorine pump 12 is used to store the liquid refrigerant transported by the second heat exchange system 200 and provide power for the liquid refrigerant, and transport it to the water-refrigerant heat exchanger 13 so that the liquid refrigerant is heat exchanged with the heated cooling water. It can be seen that the second heat exchange system 200, the fluorine pump 12, the water-refrigerant heat exchanger 13 and the compressor 11 are connected in sequence through pipelines to form a refrigerant circulation loop.

[0043] It can be understood that in the embodiment of the present application, the dry cooler can also include a cooling water system for conveying cooling water, which conveys the heating cooling water to the first heat exchange system 100, and conveys the cooling cooling water conveyed by the first heat exchange system 100 to the computer side, for example, to a liquid cooling device, to cool the computer. Exemplarily, the water-refrigerant heat exchanger 13 in the first heat exchange system 100 includes a refrigerant inlet, a refrigerant outlet, a water inlet, and a water outlet, wherein the refrigerant inlet is connected to the fluorine pump 12, and the refrigerant outlet is connected to the compressor 11; the water inlet and the water outlet are connected to the cooling water system.

[0044] It can be seen that in this embodiment, the cooling water can be cooled after passing through the dry cooler. For example, by adjusting the output parameters of each component in the dry cooler, the temperature of the cooling water can be reduced to a preset value to meet the requirements of the computer system for the cooling water temperature. Specifically, the refrigeration process of this embodiment includes the air side process, the refrigerant side process and the cooling water side process of the circulation flow. Among them, the nodes of the air side process are: outside air, wet curtain, dry coil, fan, outside air. The nodes of the refrigerant side process are: compressor, fluorine pump, water-refrigerant heat exchanger, compressor. The nodes of the cooling water side process are: cooling water return, water-refrigerant heat exchanger, cooling water supply. In this way, the circulation flow direction of the refrigerant and the circulation flow direction of the cooling water are realized, and the heat exchange between the cooling air and the refrigerant and the heat exchange between the refrigerant and the heated cooling water are utilized to realize the cooling of the cooling water, improve the heat dissipation capacity, and ensure the stability of the operation of the IDC system.

[0045] Embodiment 3

[0046] This embodiment adds air inlet optimization and air outlet optimization to the second heat exchange system of the second embodiment. In practical applications, the second heat exchange system may include a box for setting a wet curtain, a dry coil and a fan. The box is provided with an air inlet and an air outlet, and a heat exchange air duct is formed between the air inlet and the air outlet. The wet curtain, the dry coil and the fan are sequentially arranged in the heat exchange air duct along the direction from the air inlet to the air outlet, that is, the air first passes through the wet curtain, then contacts the dry coil, and then is discharged through the fan.

[0047] Figure 4 FIG. 2 shows a schematic diagram of the structure of the second heat exchange system in this embodiment. Figure 4 As shown, the air inlet of the second heat exchange system is provided with an air guide hood 26, wherein the surface of the air guide hood 26 may be provided with openings. Optionally, the wet curtains 21 in the second heat exchange system may be provided on both sides of the system, and air guide hoods 26 are added on both sides. Specifically, straight and / or curved air guide hoods may be added. By providing an air guide hood on a single dry cooler or multiple dry coolers in the IDC room, and setting a certain opening rate on the air guide hood, the dry cooler can be helped to optimize the active airflow organization, so that more outdoor air can be effectively guided to the front of the wet curtain, thereby improving the utilization rate of the external air cooling, and the air guide hood assemblies of multiple dry coolers can also coordinate and balance the distribution of outdoor air, and balance the cooling capacity of the dry cooler group.

[0048] like Figure 4 As shown, an exhaust hood 27 is provided at the air outlet of the second heat exchange system, i.e., around the outer side of the fan. The exhaust hood 27 is arranged to be wide at the bottom and narrow at the top in the height direction. The height of the exhaust hood can be adjusted according to demand. The exhaust hood with a wide bottom and narrow top can help increase the air volume and pressure of a single fan in an aerodynamic way, thereby improving the heat dissipation capacity of the dry cooler without changing the power.

[0049] It can be seen that in this embodiment, air inlet and air outlet optimization components are configured on the dry cooler to actively create airflow organization for the dry cooler, thereby reducing the restrictions and influences of product layout and improving heat dissipation capacity.

[0050] Embodiment 4

[0051] This embodiment provides a control method for a dry cooler. Figure 5 FIG. 4 is a flow chart showing a control method of a dry cooler provided in this embodiment. Figure 5 As shown, the control method of the dry cooler includes the following steps:

[0052] Step S510: Based on the refrigeration information and energy consumption of the dry cooler, determine a target working mode from a plurality of working modes; wherein the plurality of working modes correspond to a plurality of groups of output parameters respectively. Here, the dry cooler may be a dry cooler according to any of the above embodiments.

[0053] Step S520: Determine an output parameter of at least one component in the dry cooler based on the target operating mode.

[0054] Optionally, the method can be implemented by a controller of a dry cooler. Exemplarily, the controller can be used to control a single dry cooler to implement a stand-alone control logic of the dry cooler. The controller can be connected to at least one component in the dry cooler to control the components according to the above output parameters.

[0055] Exemplarily, in step S510, the refrigeration information of the dry cooler may refer to parameter information used to characterize the refrigeration effect of the dry cooler, including the water temperature of the cooling water in the dry cooler, the refrigeration capacity, etc. Optionally, a sensor may be provided in the dry cooler to sense the water temperature of the cooling water in the dry cooler and / or the refrigeration capacity of the dry cooler in real time.

[0056] Exemplarily, in step S510, the energy consumption of the dry cooler may include energy consumption such as water consumption and power consumption of the dry cooler. The water consumption of the dry cooler may be sensed by a flow sensor. The power consumption of the dry cooler may be sensed by a power sensor, or may be calculated based on the output power of each component of the dry cooler (e.g., fan power, compressor power, fluorine pump power, etc.).

[0057] Exemplarily, in this embodiment, one working mode corresponds to a set of output parameters, or in other words, one working mode is determined based on a set of output parameters. Multiple working modes may include working modes corresponding to different energy consumption requirements and cooling requirements. In practical applications, multiple sets of output parameters can be designed in advance for different energy consumption requirements and cooling requirements, and adjusted through experimental analysis to obtain working modes suitable for different energy consumption requirements and cooling requirements. When the dry cooler is in a certain working mode, the dry cooler operates using the output parameters corresponding to the working mode.

[0058] For example, in this embodiment, the target working mode may refer to a working mode suitable for the current situation of the dry cooler. The controller may periodically determine the target working mode and adjust the output parameters of the dry cooler to adapt to the real-time energy consumption and cooling requirements. The controller may also determine the target working mode and adjust the output parameters of the dry cooler when the cooling information of the dry cooler meets the preset conditions, so as to save energy consumption while meeting the cooling requirements.

[0059] In practical applications, the controller can input the refrigeration information and energy consumption of the dry cooler into a set mathematical model, and use the mathematical model to perform calculations, and the calculation results can represent the target working mode. Alternatively, when the refrigeration information of the dry cooler meets the preset conditions, the controller can input the energy consumption of the dry cooler into a set mathematical model, and use the mathematical model to perform calculations, and the calculation results can represent the target working mode. Optionally, the current energy cost can also be input into the mathematical model, such as the current electricity price, water price, etc.

[0060] As an exemplary implementation, in the above step S510, based on the refrigeration information and energy consumption of the dry cooler, a target working mode is determined in multiple working modes, including: when the refrigeration information of the dry cooler meets the preset conditions, based on the energy consumption and energy cost of the dry cooler, the target working mode is determined in multiple working modes. The preset conditions are conditions that meet the refrigeration demand, such as the water temperature is less than the first preset value, the cooling capacity is greater than the second preset value, etc. For example, the controller can calculate the power and water consumption in real time when the refrigeration demand is met (for example, the water temperature and cooling capacity reach the preset values), and perform comprehensive calculations in combination with the current electricity price and water price to determine the working mode suitable for the current situation.

[0061] Exemplarily, each of the above-mentioned multiple groups of output parameters may include output parameters of at least one component. Among them, at least one component may include, for example, at least one of the fluorine pump, compressor, spray water pump, and fan in the above-mentioned embodiment. After determining the target operating mode, the controller may use a group of output parameters corresponding to the target operating mode as the output parameters of the above-mentioned at least one component, that is, control the output of these components.

[0062] Optionally, in this embodiment, multiple working modes under different control targets may be pre-set, such as energy efficiency priority mode, water saving priority mode, cost priority mode, etc. Based on the output parameters corresponding to these working modes, the operation of the dry cooler can be controlled, so that the operating effect of the dry cooler meets the control target corresponding to the working mode. In practical applications, the performance of multiple groups of output parameters in terms of energy efficiency, water saving, cost, etc. can be analyzed / statisticed through experiments, so that output parameters with energy efficiency advantages, output parameters with water saving advantages, and output parameters with cost advantages can be selected from multiple groups of output parameters, and the working modes under the above-mentioned multiple different control targets can be configured based on the selected output parameters. In practical applications, the user can set the dry cooler to be controlled by a pre-configured priority working mode, or manually select a specific working mode to control the dry cooler, or set the above steps S510 and S520 to be used for adaptive control of the dry cooler.

[0063] It can be seen that the dry cooler integrated energy efficiency optimization program in this embodiment can actively seek optimization according to the dry cooler energy efficiency and environmental conditions, thereby optimizing the operating state of the dry cooler through intelligent control and improving the heat dissipation capacity under the premise of the same energy consumption.

[0064] Embodiment 5

[0065] This embodiment provides a control method for a dry cooler. Figure 6 FIG. 4 is a flow chart showing a control method of a dry cooler provided in this embodiment. Figure 6 As shown, the control method of the dry cooler includes the following steps:

[0066] Step S610: Based on the refrigeration information and energy consumption of at least some of the multiple dry coolers, determine at least one started dry cooler from the multiple dry coolers, wherein the multiple dry coolers include the dry coolers provided by any of the above embodiments.

[0067] Optionally, the method can be implemented by a controller connected to multiple dry coolers. Exemplarily, the controller can be used to control multiple dry coolers to implement group control logic of dry coolers. Here, group control logic refers to comprehensive monitoring and allocation of the refrigeration capacity of the dry cooler group based on the controller.

[0068] Exemplarily, the at least some of the dry coolers refer to all or some of the multiple dry coolers. For example, the multiple dry coolers are all dry coolers in an IDC room, and all or some of the dry coolers in the IDC room have been turned on. Based on the cooling information and energy consumption of the turned-on dry coolers in the IDC room, at least one turned-on dry cooler can be determined among all the dry coolers in the IDC room, and then the determined at least one turned-on dry cooler can be turned on, and other dry coolers in the IDC room can be turned off.

[0069] Optionally, the method may further include: determining an output parameter of at least one activated dry cooler. In practical applications, affected by certain factors, some dry coolers may fail to reach a predetermined cooling capacity in certain air dead spots and locations with high solar radiation. According to the method of this embodiment, the controller will actively intervene to coordinate the activation of dry coolers with cooling potential and increase the cooling capacity to meet the total cooling capacity requirements and avoid the risk of insufficient cooling capacity.

[0070] It can be seen that the embodiment of the present application can improve the heat dissipation capacity by adding a first heat exchange system to the dry cooler. Optionally, the embodiment of the present application also reduces the limitations and influences of the dry cooler product layout by configuring air inlet and air outlet optimization components. Optionally, the embodiment of the present application also provides an energy efficiency optimization program to achieve automatic optimization through single-machine control logic and group control logic. Through the above-mentioned improvements in many aspects, the embodiment of the present application can effectively improve the heat dissipation capacity of the dry cooler and ensure the stability of the IDC system operation.

[0075] If the memory 710, the processor 720 and the communication interface 730 are implemented independently, the memory 710, the processor 720 and the communication interface 730 can be connected to each other through a bus and communicate with each other. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 7 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0076] Optionally, in a specific implementation, if the memory 710, the processor 720 and the communication interface 730 are integrated on a chip, the memory 710, the processor 720 and the communication interface 730 can communicate with each other through an internal interface.
